Hydraulic suspension device, control method and device thereof and automobile

Abstract

The invention discloses a hydraulic suspension device, a control method and device thereof and an automobile. The hydraulic suspension device comprises a suspension shell, wherein one end of the suspension shell is provided with a rubber lining; the other end of the suspension shell is provided with a connecting shell; a flow channel plate is arranged in the suspension shell; a first liquid chamber is formed between the flow channel plate and the rubber lining; a rubber leather cup is arranged between the flow channel plate and the connecting shell; a second liquid chamber is formed between the flow channel plate and the rubber leather cup; a spiral flow channel is formed in the flow channel plate; one end of the spiral flow channel is communicated with the first liquid chamber, and the other end of the spiral flow channel is communicated with the second liquid chamber; the first liquid chamber is communicated with a decoupling chamber; a decoupling membrane is arranged in the decoupling chamber, and is used for partitioning the decoupling chamber into a liquid chamber which is communicated with the first liquid chamber and an air chamber which is communicated with the atmospheric air; and a channel where the air chamber is communicated with the atmospheric air is provided with a valve. In the technical scheme of the invention, the hydraulic suspension device can have higher vibration isolating performance under high-frequency vibration and low-frequency vibration.

Description

technical field [0001] The invention relates to automobile vibration reduction technology, in particular to a hydraulic suspension device, a control method thereof, a control device and an automobile. Background technique [0002] With the continuous development and progress of automobile technology, people have higher and higher requirements for the comfort of car driving and riding, and the vibration and noise generated by the car engine during operation are an important factor affecting the driving comfort of the car. Therefore, in The engine and body of the automobile are usually connected with a vibration-damping suspension to provide vibration isolation between the engine and the body and reduce the impact of engine vibration on the body. [0003] At present, the vibration damping suspension device of automobile usually adopts passive hydraulic suspension device, which mainly includes: two liquid chambers filled with liquid, and the two liquid chambers are connected th...
